BACKGROUND OF THE INVENTION

This invention relates generally to the field of packages and containers, and in particular, pertains to containers having two compartments and that may be used to keep two components separate until use.

It is desirable to fit a device to the top of a beverage that can dose or supply a product. It is also an advantage to the consumer to provide a dispensing method once the dose or supply has been delivered to the main receptacle vessel.

Twist to open technology provides limited opening port increased operational forces and a steep learning curve for use by the end user. Ingredients housed are often compromised when the mating components are not properly aligned. This failure breaches the seal integrity for the ingredients and may not be readily known by the manufacturer or the end user. These devices may also contain multiple parts to achieve the actions needed to house product and twist to dispense. Other products require a great deal of force to open the closure and is commonly opened by slamming the head of the closure down onto a hard surface in order to breach the sealed portion of the closure thereby allowing access to ingredients.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner.

The present invention provides a point of use dispensing device that will supply fresh healthy ingredients that are stored inside the closure. The device is used to store ingredients protecting them from UV light and moisture at minimum. The closure will be intuitive for use and easily operated by the end user. The new device minimizes components and materials while maximizing the dispensing port.

A dispensing closure 100 is used to house or carry the dose or supply that when activated delivers the dose and allows the end user to dispense the product as desired without the removal of the dispensing closure from the bottle or container.

The closure radial skirt 110 to which threads are typically used but not limited to for attachment to a vessel opening. The vessel opening is sealed via a depending radial member 110 used to interferingly engage the opening portion of said vessel. The depending skirt 110 shown (in FIGS. 9-10) has a frangible TE skirt 120. The depending skirt 110 can be used with or without the depending TE skirt band 120. The closure may also employ the use of a foil liner 130 to add to product efficacy and tamper evidence. Depending from said skirt 110 is a tube 140 at the distal end of the tube is a dome portion 150. The dome portion can be but is not limited to a thin uniform wall section that can be readily deformed when sufficient force is applied to said dome. The dome is configured with two hinge elements 160, 170, one at the radial edge of the tube 160 and one at the radial edge of the septum 170. The said hinges are configured in a manner to allow the dome to flex to a maximum inverted position and at the apex of said dome a depending septum 180 extends toward the base of the closure. The distal end of the septum is configured to receive an end cap 190 in mating engagement. A foil liner 130 can be applied over said end cap 190 and distal end of the tube 140 sealing the interior of the tube 140. The closure tube 140 and dome 150 features can be further improved by adding a tamper evident truss 200. The truss 200 has an outboard hinged attachment 210 to the tube. The truss also has a break-away attachment 220 centered to the dome and truss between the outer dome and the truss. A space is provided between the truss configuration and tube of the closure and the convex dome for ease of customer use. The truss 200 and break away attachment 220 are also used to prevent the dome from premature inversion in the event a vacuum is formed on the end of the closure inside a vessel.

The closure is activated by moving by pressing on the truss 200 in a manner to fold it away from the dome 150 top. The folding motion shears the break away attachment 220 and is hingedly pivoted beyond the outer edge of the dome toward the radial edge of the tube. The truss 200 is configured to have interfering engagement with the radial edge of the tube to prevent the truss from moving back over the dome. The ingredients inside the tube are released by pressing downwardly onto the dome 150. This action directly acts on the depending septum 180 which is attached to the end cap 190. The end cap 190 is in interfering engagement with the tube 140 sufficient to provide sealing integrity alone as well as the depending septum 180. The dome 150 is pressed downwardly until it inverts and will remain in a now concaved configuration. The septum 180 has moved vertically downward pressing the end cap 190 from its assembled position below the distal end of the tube 140. This motion also breaches the seal of the foil lining 130 allowing the ingredients inside the tube 140 a path way out of the tube 140.

The dome 150 structure can be designed to have a plurality of radial hinge members 160, 170 that are spaced apart throughout the arc of the dome 150. The dome 150 can be configured to contain depending radial ribbing. The end cap 190 can be configured to include a liner in between the end of the septum 180 and the bottom portion of the end cap 190 to provide sealing interface and added removal resistance. The dome 150 can be configured to have a surrounding structure 240 to prevent inadvertent actuation. The end cap 190 and tube 140 can be configured with interfering sealing engagement with a highly polished mating surfaces. These highly polished faces when in intimate contact provide a superior seal integrity against moisture. The materials of the closure 100 and end cap 190 are primarily comprised of propylene and ethylene materials for the preferred embodiment. Alternate materials of flexible nature can also be employed like thermoplastic elastomers and others of a lower modulus sufficient to provide flexibility. The upstanding ring 240 around the dome may be configured with one or more ports or openings to allow easier user access or to drain water after washing.

The invention provides a dispensing closure 100 used to house a secondary supply or dose of product. When the closure is activated the secondary product or dose is dispensed into the main vessel to which it is attached. The inverted dome is a one piece delivery method to supply a dose or supply of product into a vessel to which it is attached. The inverted dome is configured with a septum 180 and a thinner convex dome 150, and an end plate seal 260. The end plate seal 260 can be made from a variety materials that are thin and frangible in nature to fracture when the thinned dome 150 is inverted to a concave shape. The septum 180 applies force against the end plate 260 shearing and fracturing the end plate when the dome is inverted.

The concept can be improved by adding a tear away protective portion 270 which extends above the apex of the dome to prevent accidental inversion of the dome. The tear away band 270 can be configured to extend from the cylinder 140 to which the dome 150 is attached or from the deck 280 of the threaded portion 290 of the cap. The concept can also be provided with a removal protective overcap 300 to protect against accidental inversion of the dome 150.

The concept can be improved by adding a septum end attachment 310. This separate attachment is used to capture a foil seal 130 type of end plate 260. The septum end attachment 310 is configured in a manner to apply uneven pressure on the end plate 260 to reduce the force required to fracture or open the end plate 260. The septum end attachment 310 is generally reduced in diameter from the dose chamber 320 to allow free movement of the septum 180 and dome 150 inversion. The septum end 310 is configured to include a radial bead 330 and is largely cupped in configuration. Once the dome 150 is inverted and septum end attachment 310 acts against the end plate 260 in sufficient force to break away the seal plate 260. The seal plate 260 being flexible enough to accept the cup shaped septum end attachment 310 and hold the flexible seal 260 within the radial beads 330 positioned to the inside of the cupped end of the septum end attachment 310.
